cub wont start help

Postby gpcubboy » Sun Apr 07, 2013 5:56 pm

Last weekend went out to start my 1952 cub. It would not start it was last ran about 3 months ago. My cub has always been a little cold blooded to start compared to my 9n ford. Usually after 3 or 4 attempts of starting it will start. Then have to partially choke first time you speed it up to keep it from dieing. Last week i did my usual routine wouldn't start it would hit once unchoked and would hit twice when partial choked. If you pulled choke lever back all the way and tried it wouldnt hit at all and if leave it choked too long fuel dripping out filler ball in bottom of carb body. I drained tank of fuel and emptied/cleaned sediment bowl, cleaned fuel line, replaced with new clean fuel today. Tried again same results identical to last week no change after 15 minutes of trying. Left sit went back couple hours later same symptoms. I am assuming maybe a stuck float or dirty adjustment screw. Never been inside the carb on a cub. Have worked on all types B & S carbs over the years. Never considered myself an expert carb person by any means. My cub burns some oil also thought possibly fouled plugs or both. I looked at cub book of knowledge and cub faq parts of site. This cub always a little hard to start even when my grandfather owned it who passed away 3 years ago. This is the first tractor i learned to drive at age 9 and has alot of special memories for me about my grandfather. It is tearing me up i cant get it to start. Any help much appreciated on this problem.

If its an IH carb, try cleaning the main jet. (Brass hex head, on the outer side.) Use a thin wire (Telephone wire is perfect.) Could be a little speck, blocking it. Try spraying starting fluid, or carb cleaner,into the choke area, and try starting it. If the carb is plugged up, it will run briefly, on the fluid you spray in. Has it been tuned, recently? could be no spark. Ed

No i haven't checked spark. I should of thought about doing a spark test. I tend to shy away from tearing into something on it because it has so much sentimental value to me. Thanks for the advice on everything.

Proper maintenance is part and parcel of owning a Cub or any machine for that matter. Suggest you spend a little time reading the McCormick Farmall Cub Tractor Operator's Manual 1-5-55. It is a bit later than your '52 but it all applies. You can find the maintenance section starting on page 13 with the Lubrication Section. The Maintenance section begins in ernest on page 23.

By the way, congrats :applause: on becoming the keeper of your Grandfather's Cub. This is truly special, to be able to have a Cub that has such a strong family connection and personal ties.

When was the last complete engine tune up?

Same opinion as Ed and Bill, could easily be an ignition problem.
I have an excuse. CRS.

Success :D I am so happy I got time to work again yesterday on Grandpa's 52 cub I call Virgil after my grandfather. I was able to get it started after some work and using advice from the forum. I cleaned the main jet and it had some dirt in the opening on the side of the carb. Next I replaced the spark plugs. I have pictures of the old ones. Last week I had drained the old gas out, cleaned the sediment bowl, the carb inlet, and the fuel line and it still wouldn't start. Once I replaced the plugs and cleaned the jet I tried it again it rolled over about 1/2 a turn on the starter unchoked and started right off. It hasn't cold started that easy and without choking ever that I can remember. Thank you ScottyD's Dad, Wakulla Bill, Eugene, Rudi for the welcome and info. Thanks Brian for the posts, phone conversations, and offering to stop by this week and look at it. Guy's I appreciate all your help and advice. I apologize for not putting up an introduction post to the forum when I became an official member of the forum but I was so focused on my problem. I have been a viewer for a year or so now. I will post an intro. later tonight though. Again I can't thank you guys enough you are the best. I had the biggest smile last night I had in a long time. Here is a photo of plugs:
