Amal 76 and Amal 276

Thanks, John

The bike actually runs well, starts easily hot or cold (easier than my electronic ignition Dommie whatever the weather)so I am not desperate to improve something that's no fun to ride - but it does seem to be very thirsty which is most of the reason for trying to get it to work properly. I put its thirstdownto side valve inefficiency - your Model 18 with new-fangled overhead valves should be a lot better anyway. Now the weather is looking a bit better, I think I'd better ride it rather than play with it in the garage.

Thanks Richard. I now have type 1 and type 2. Perhaps a type 3 will pop up next if I keep my eyes peeled. Maybe the pilot screw itself is wrong! I think I'll check the galleries in the block yet again. It amazes me how small the holes are and what a difference it makes if they are not correct.

I did consider drilling the outer holes round the bottom but that's a permanent external change I'd prefer to avoid.

Thanks for all the texts and pics. I'mgoing to go for a new carb as I'm not happy with low speed running. Top end is fine - took it up to 60 yesterday with no bother at all. (Shame about the lack of paint on new carbs spoiling the looks but that's another issue).

I see Feked and others supply a Wassel version of the type 76 - with the body holes. Burlen only do the 276 (with the central hole in the block I believe). Part of me says "Buy British from Burlen" and part of me says "buy the correct looking one even if it is a 'reverse engineered' product from somewhere else". I suppose it's too much to hope that anyone has done back to back comparisons? If not, I'll play safe and go for Burlen.

Sorry to drag this thread up again but I think an update might be in order. Last year I bought a new 276. It's not a total success. Issues include flooding through the overflow above the bottom nut. That has to happen if it is tickled too much. But pick up on blipping throttle in a gear change is non existent. After about 60 miles today I decided to lift the needle. It should be in the middle but is already at number 4 of 5 being nearly as high as it can go. I'll try one more lift maybe. Is that the right move?

Thanks Robert. I just took for a short run. The pilot screw has no effect whatsoever from fully in to 2 or 3 turns out. But it does start easily and tickover is faultless. I'm suspecting the slide but that's a costly and fiddly exercise. I'll just use it...
