89 Carbuetted TB42 Idle problems
Hi, hopefully somebody out there has had this same problem, as its driving me mad not being able to find the cause.
Basically she runs smooth as butter, but she will not idle properly, once you back off the throttle she will idle at about 350 rpm for about 7 - 10 seconds then completely die, another symptom shes doing is say I was cruising along in 3rd gear at 2600 revs or something around that, and I put the clutch in straight in ,take my foot straight off the throttle and roll/brake to a stop (say at a set of lights) she will idle really high at about 2000 rpm, but as soon as I give it a little stab of throttle it will drop down to about 350 again then die soon after.
Due to my model being fitted with points, and the fact that I know they have not had attention lately, I whipped them out and they were stuffed, so I put new points, rotor button and distributor cap on, (the leads were already new, as were spark plugs) and she still does the exact same thing, so I am happy to rule out the ignition side of things being the problem, My gut is telling me it needs a carby kit put through it, but I'd rather not jump straight to that option as its not the cheapest. I have checked all vaccum lines and none are split or perished, and it doesn't appear to be losing vaccum anywhere. It has me absolutely stumped.
Has anybody else had this problem with a carburetted tb42 patrol before?
I should mention its on dual fuel, but it does the exact same thing on both fuels, so its nothing to do with the gas or petrol system inpacticular I dont think
Thanks
