Colby Posted Friday at 07:15 AM Report Share Posted Friday at 07:15 AM Hello everyone, I have a 73 Bultaco Alpina M 85 with a Amal carb. The bikes motor has been rebuilt & it has the original Amal carb on it which I have rebuilt with all new gaskets, float, & screens. My problem is the tickler will not tic over. I have talked to Hugh’s Bultaco here in the states & he said the new gaskets are thicker & that might be stopping the plunger from pushing on the float. I’m going to remove the cab & inspect the plunger to see if it comes apart. Has anyone ever had this issue before? Because without the bowl flooding over, these bikes are hard to start. Thanks, Colby Quote Link to comment Share on other sites More sharing options...
stevem75 Posted Saturday at 12:27 AM Report Share Posted Saturday at 12:27 AM Lean the bike over on its left side until fuel flows out the tickler hole . That will over flow the float bowl the same way the tickler would. Try that and see what happens 2 1 Quote Link to comment Share on other sites More sharing options...
feetupfun Posted Saturday at 12:42 AM Report Share Posted Saturday at 12:42 AM As well as the gasket thickness, the new float may be slightly different shaped, causing the tickler to miss it. I had the same issue with the tickler not pushing the float down on the same carby. I didn't pursue a solution because I didn't like the carby anyway and fitted an OKO 1 Quote Link to comment Share on other sites More sharing options...
lorenzo Posted Saturday at 09:12 AM Report Share Posted Saturday at 09:12 AM (edited) Colby - John Healey is a recognised authority in setting up and using Amal Carbs. Here's what he had to say to a user with the same problem as yours :- "First you must establish that the float level is proper. The tickler travel is determined by how far the roll pin is pressed into the button. The travel is adjustable. To increase the travel pull the pin out of the button a tad. This is easily done with a diagonal cutting pliers (not electricians pliers!). Push the button to exend the pin out of the body as far as it will go. Grasp the pin firmly (it is hardened steel) at the point it is just exiting the body with the diagonal pliers and lever the pin out. Be careful that you don't mark the float bowl gasket face. You should be able to get another 1/8" or so of travel. This should solve your problem. " (I'll add that I haven't actually tried it myself as none of my carbs have ever displayed the problem.)
