Pullstart 58,780 #1 Posted March 12, 2016 So a while back I picked up a C-101 with a broken rod. Today I swapped in another 10 horse from my parts tractor and while I assume I hooked everything up correctly, I am stumped to find no spark. The coil appears to be new, really all I had to re-wire is the positive coil wire, starter positive and grounds, and the charging circuit. Assuming this tractor was running fine when the rod broke, is there something I should look for to get me some spark? I'm going to go out and swap the condenser over too and check the points gap. 1 Share this post Link to post Share on other sites
953 nut 50,999 #2 Posted March 12, 2016 Cleaning the points would be my first step. Also, put a test light or meter on the coil + to see if you are getting 12 volts. Good luck. 3 Share this post Link to post Share on other sites
Pullstart 58,780 #4 Posted March 12, 2016 I've got 12.44 volts to the coil with the ignition on, the points gap is set at .020 and they look clean to me. The condenser is attached to the negative side of the coil. Is that all kosher? Share this post Link to post Share on other sites
953 nut 50,999 #5 Posted March 12, 2016 That all sounds good, how about a different plug wire and plug? Share this post Link to post Share on other sites
Pullstart 58,780 #6 Posted March 12, 2016 Yeah tried that too. The donor engine supposedly ran good before I picked it up, maybe I'll swap the coil even though it "looks" older. I'll also scuff the points again and recheck the gap while I'm at it! Share this post Link to post Share on other sites
953 nut 50,999 #7 Posted March 12, 2016 You may want to disconnect the wire from the coil to points, check for continuity to ground while turning the engine over. Should be shorted to ground the majority of the time, only time it wont be grounded is when points open. Also the condenser may be bad; you can run without one for a test without harming the points. 1 Share this post Link to post Share on other sites
Pullstart 58,780 #8 Posted March 12, 2016 Moral of the story, "points look good" isn't good enough. She runs! Thanks for your help Richard, it's amazing how fast small little problems can be solved with a couple gearheads troubleshooting together! I have a pretty good gas leak at the petcock, so I'll try the spare bushing out of the parts tank. It seems pretty tight compared to the one on the tractor. Then I'll pull the tins from the engine and give it a good bath! There's quite a bit of grass packed in there, she'll be real happy when she has good cooling again! 1 Share this post Link to post Share on other sites
Daddy Don 887 #10 Posted March 13, 2016 Good looking horse. Like the battery hold down. That gives me an ideal on how to do mine. 1 Share this post Link to post Share on other sites
elcamino/wheelhorse 8,943 #11 Posted March 13, 2016 I understand that brand of battery hold down comes in different lengths. 4 Share this post Link to post Share on other sites
Daddy Don 887 #12 Posted March 13, 2016 How much does the hold down cost per foot? 2 Share this post Link to post Share on other sites

C-101plowerpower 1,589 #14 Posted March 13, 2016 have you tried filling the plug with new sparks? 4 Share this post Link to post Share on other sites
Pullstart 58,780 #15 Posted March 13, 2016 I can't take credit for that hold down, it was like that when I picked it up. Literally I swapped engines, checked the oil and turned the key. (Then had to troubleshoot...) It even held a charge all winter! power, it's great! Before dark and a bonfire with my girls I put the RD deck on and cut a path through the lawn. This will be a great beast for leaf duty! Share this post Link to post Share on other sites
