When i pull away in first i have to really feather/ride the clutch and give it quite alot of right pedal. there is never any fear of wheel spinning because if let the clucth up to quick it would just stall.

I thought it might be the ignition timing but i have tweaked that and it is still the same.

The car is driveable but i cant help thinking it could be better.

I also sometimes have problems getting it into first. i have to go into second then into forst that way.

I am thinking a clutch problem so will start tomorrow with bleeding it and re filling it.

Can anyone shed any light on what the problem could be?

have you stole my car lol mine is the exact same!

i got rid of most of the boggin by setting the points with a dwell meter. also check your fueling, use a colour tune if you can, this really helped me.

Is your tickover ok? as this will cause bog, and iv found that why i cant get it into first sometimes. try getting you revs up befor changing into first.

[miniboo]

tickover and fueling and ignition all ok.

tickover and fueling and ignition all ok.

how did you set your ignition, and idle speed?
only other thing i spose it could be is the valves then have you set your tapets latly.

I have the same problem too so I have mastered my double-clutching.

I think mine might be due to cam timing.
Could some one shed some light to hels us all with this problem?

Thanks in advance.

What does double-clutching do for you that addresses this problem?

Matt, have you confirmed the oil level in the carb dashpots? If you're still running a stock/standard needle in the carb perhaps you could benefit from a richer one. What do the spark plugs look like if you run the car at speed, switch off, coast to a stop and check their color? (A high-speed run followed by decelerating in gear, and idling will mask the results... switch off and stop with the car in neutral to get a good color indication).

just been looking at some other stuff on the new and could be something with the advance either with the vac or the counter wights?

[dklawson]

If the problem is related to the distributor, it may be associated with stuck advance weights or broken springs for the same. However, it's not likely to be related to the vacuum advance. Typically the vacuum advance only comes into play at part throttle to increase your cruising fuel economy.

Well by double-clutching I can shift into 1st gear no problem. I do it to shift into 2nd gear too, because sometimes (only sometimes) it won't go into 2nd gear coming from 3rd and this is very annoying when taking corners, double-clutch seems to take care of the problem.
Most of the time it won't shift into 1st even at full stop without having to shift into 2nd gear first then into 1st gear

PS. I don't have the pulling away (clutch riding) ploblem though...

BJst416, which gearbox do you have?

I only ask because the Mk1 gearboxes were typically 3-synchro units and were not meant to engage 1st gear (when downshifting) until you come to a full stop. You can double-de-clutch them into 1st if you really want to but it's not necessary and puts undo wear on parts that are hard to replace. Forgive my ramblings if you've got a later gearbox.

[luke6040]

na thats intersting to kno, I have an A+ box dunno about the others, whats all this double-de-clutch i hear it alot but im to imbaressed to ask?

[dklawson]

Double clutching (or double-de-clutching) seeks to match the speeds of the gears in the transmission so they will mesh with each other during gear changes without grinding. When you describe using double-clutching down from 3rd to 2nd or 2nd to 1st, that's double-de-clutching.

Double-clutching is done "up" through the gears. You push in the clutch, shift out of the lower gear into neutral. With the gear lever in neutral you release the clutch pedal then quickly push the clutch back in and move the lever to the higher gear.

Double-de-clutching is a little more complicated and is done when shifting "down" through the gears. With the car in the higher gear you press in the clutch and move the gear lever to neutral. You let the clutch pedal out and simultaneously BLIP the throttle to rev the engine. With the engine RPM still high you push the clutch in and select the lower gear.

In double-de-clutching coordinating the reving in neutral to achieve the right RPM only happens with practice. Double-clutching up through the gears by comparison is easy.

[BJst416]

Nothing to forgive, I appreciate you putting yourself in different scenarios to try and figure it out.

Mine is a 93 carb A+

I would imagine that by 'double-clutch' or 'double-de-clutch' you would actually prevent some of the wear on the synchronizers in the later gearboxes?

[miniboo]

oil is topped up in the dashpot.

i am using megajolt for my ignition so no dizzy to worry about. like i say all the otehr times woth driving about it is fine. just when pulling away. its like i am trying to pull off in 3rd gear(i am defo in first by the way)
