I am working on my 1975 Trident that had not run in 35+ yrs. Among other things, I put in a Boyer ignition and just finished rebuilding the carburetors. I have new tubes connecting the carbs to the engine. The tubes are very tight on the intake and carb side. I have not been able to line everything up and push all 3 onto the intake side all at once. I have tried the reverse approach too. I tried soaking the tubes in hot water along with using soap for a lubricant. Does anyone have any experience with this or ideas I might try. Thanks in advance for any help.
