I now have 2 Massey tractors, a 1952 pacer and now a 1959 TO35. both use the Marvel carburetor. Neither tractor will run at anything above idle without holding the choke fully closed. They idle very smooth. The TO35 has a main jet adjustment screw that the Pacer does not but enriching it does not help. Both have had the carbs rebuilt and the fuel is clean and fresh. Any help would be appreciated. Also do you know if the Marval is the proper carb for the TO35? The tractor came with spares and there is a Zenith carb in the box of spares also.
Thanks

Hi Steve,

Most of these engines don’t have any timing marks. The only references provided are the timing pin hole in the flywheel (also TDC and BDC marked on the flywheel – visible only if you split the tractor) and timing leters inside the injector pump. Timing this engine is achieved using a sequence of measurements and adjustments, which must be followed exactly. It is quite an involved process, but anyone can do it if the procedure is followed correctly. The process is explained on the 23C Engine DVD.
