Hello Folks,
Last autumn, I swapped the carburetor (with a rebuilt unit from Rock Auto) in my stepfather's 1984 Toyota Motorhome. It has the 22R engine with about 75,000 miles on it. We are located in the US so it has the standard US emissions equipment for that model year. Given it's age, when I made the swap I replaced all of the vacuum tubing--all 59 miles of it LOL.
It started and idled good, and we were able to run the RPMs up to the high range (while sitting) with no problems. However, when we took it on the road it would hesitate and almost stall when I would accelerate with the gas pedal in the middle range. It would accelerate if I floored it, and it maintained speed on level ground, but the hesitation while accelerating is bothersome.
While swapping the carburetors, I was very careful to mark the vacuum hoses so they would be placed in the proper locations in the new carb.
Since I live 400 miles from my stepfather's home, and was limited in the amount of time I could spend there, I did not have the time to troubleshoot and possibly find solutions to this problem last October. I plan on visiting him next week and hope to try to fix this once and for all.
If anyone would have suggestions that I can try, I would appreciate it. One possibility might be the distributor advance; can someone suggest what to do to see if that is the problem (please note that this motorhome had not been used in quite a few years so there may have been dry rot of rubber/flexible parts)? There are multiple adjustments on the carburetor; should I try one or more of them?
Thanks in advance for your help and advice.
