Need help with a Bobcat 642 (ford 1.6) Mod # 2274E motor

Old Machinist, Have you or any of you folks used any of the electronic conversion kits. I thinks I read of someone using them but I would like to get some positive feed back before putting my money down. If any of you have done so what company did you go with ? Thanks again everyone for your advice. Have fun, buckshot

mr. buckshot, instead of a new governor, could a rev. limiter be used. $900.00 is a hell of a lot of legal tender. tony b.

Buckshot, I haven't done the electronic ignition on a Bobcat but I have done them on Ford tractors and it's so nice to never have to mess with points ever again. I searched for posts from other members about doing a Bobcat and many said they were going to do it but never posted any results. I assume no news is good news on those.

gtx71, A governor maintains the rpms at the throttle set level no matter how much load is on the engine. A rev limiter would not work for that.

Old Machinist, would there be any compatibility issues between electronic ignition and the governor?
The only reason I ask is that I found it odd that Bobcat still used points and condenser in my 742B (Mitsubishi 4G32 engine) in 1993.
Thanks (my apologies to the thread starter but thought that some of the rest might enjoy the discussion),

Converting to electronic ignition won't effect the action of the governor. All the conversion does is change how the ignition coil is grounded. Points open the ground circuit by just opening a gap, electronic ignition does it with a switch(thyristor).
More than likely that's way Mitsubishi supplied the industrial engines.

I put a Pertronix electronic ignition on my 742B Mitsubishi engine. It works great, engine starts as soon as the key is turned. I did have to make the hole for the gap adjustment larger because I could not get the gap closed enough but that was pretty easy with a smal round file. What really puzzled me was that after the install, the starter began turning when the key was just turned to the first click. It ended up that someone, not me, had wired the starter wrong and when I took the resistor off, since it was no longer needed, there was enough power to get the starter turning. I do have a 742 with the Ford 1.6 in it but I have not gotten around to switching that ignition yet. I will eventually however since the tune up parts for the distributer are sooooooo expensive.

^+1 If you haven't switched to electronic ignition, I highly suggest it. Before converting to electronic I bought all new ignition parts, and got the machine running pretty good for a month, but it sat 3 weeks and then started acting up again. It would backfire, causing fuel to shoot out of the carb into the air filter, at the same time the governor was jumping all around. I thought I had carb or governor problems. I bought the electronic ignition and solved all issues with the turn of the key. $282 from northern power products. Plug and play. The machine has never run better. Now I am on to the hydraulic leaks.

Hi, I know this is an old post, but any chance you still have the governor that you took off? Thanks, Mike

Greetings folks, I am helping a friend with his bobcat 642. It has a ford 1.6L engine. the engine mod #is 2274F. The engine SR is E8932/195. The date code is EB. The machine was bought needing a BUNCH of TLC. I have been eliminating a number of problems. It will now start but runs rough and then as it worms up it quits. Cant seem to get it up over a high idle. there are moments it seems to smooth out only to sputter and die. The fuel system has been totally cleaned out, new grommets in the pull tube, new tank sender, removed capped and replaced the mech fuel pump with an electric pump. The external governor was no good and has been replaced with a new one. I could not believe over $900.00 for a governor. I paid a good bit of attention to the fuel system because it seemed to be running out of gas. Now that I have redone the fuel system I guess it is not that. I am now thinking about ignition. If any of you folks can shed some light it would be great. Have fun, buckshot

i would go with electronic ignition petronix makes a conversion kit beats the heck out of points
