Have you ever had problems with the big remi's no Priming?
Umm
Not really....
I would check the fuel filter/line, carburetor inlet needle height; make sure you have the carb gaskets and diaphragms in the correct order.
Depending upon the model of Tilly carb, the hi/lo needles may have been put in the wrong holes.
Also, try starting the saw with the fuel cap loose, the tank vent could be malfunctioning, causing the fuel tank to vapor-lock.
If you have the tools, do a crankcase pressure/vacuum test, faulty crank seals can cause the saw to not start/run.
There's a slight chance it could be reed plate problems, but I've never seen any go bad... Doesn't mean it can't happen though.
Check the saw for spark too, just cuz.
You'll need to find an original Remington spark plug wrench, or modify the snot out of a scrench to get the plug out.
Almost all of my Remy's are difficult to start, I almost always have to prime them with fuel mix in the carb whenever they sit for a few months; usually always have to retune the carbs again too. About the only exception I have is a PL-7 with a primer bulb, that one always starts on the first pull, no matter what.[emoji6]
Hope this helps!
