Do you have engine cranking over?

Ask Your Own Small Engine Question
Customer reply replied 2 years ago
No crank at all only ive seen yet with battery is a small green light with a lightning bolt in it
Technician: Curtis B., Technician replied 2 years ago

If engine is cranking, do you have spark at the plug wire? Remove spark plug and with the plug grounded to metal, see if you have spark when cranking. If you have spark, put finger over the spark plug hole, and see if you have compression.

Motors spinning feely and can feel what should its compression stroke
Customer reply replied 2 years ago
The starter im only seeing 1 large nut on it from the pos cable and then a ground near the bottom
Customer reply replied 2 years ago
Tosses the battery charger on the starter and ground and shes turning over so id assume ima need a battery for it
Technician: Curtis B., Technician replied 2 years ago

Where does the positve battery cable go to? Should go to starter solenoid/relay. then on to starter ,when solenoid closes.

Customer reply replied 2 years ago
From what i can off the battery and back behind a closure here where i cant see the end then back out to the starter, when i did power to the starter i can hear it move but not see the flywheel that i turned moving at all
Technician: Curtis B., Technician replied 2 years ago

If you put positive battery cable to the staters single post, stater should engage the flywhell and spin engine. If battery voltage is above 12.5 volts. If not, the starter is bad. Or the mating gear on the flywheel is damaged! Can you get the model number from tractor and engine? Engine example will be 345656-023-B1 , not sure about the Bolens number.

I dont have a voktmeter to double check but i have a battery charger on it and thats what i used to spin the starter its running at 12vs on a 6amp charge was enough to spin it
Technician: Curtis B., Technician replied 2 years ago

Did engine spin, or just starter. If just starter, remove the starter and see if the gear is good.

Just the starter only, is it easy to remove i have low light conditions here
Technician: Curtis B., Technician replied 2 years ago

Engine numbers? Just two bolts and the cable think!

This is old flat head twin?

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 2 years ago

Older models have two bolt flange, at the top, that holds starter to side of engine. Newer models have two bolts under the flywheel that have to be removed!

Ask Your Own Small Engine Question
Customer reply replied 2 years ago
From what i can see the numbers are model: 400707 , type 1205 01 , code 88031912After trying it more time i can hear it sounds like that gear is shot tho before it sounded like clucnking around but now you can hear like it isnt even connecting on it
Technician: Curtis B., Technician replied 2 years ago
01 is the correct model number. See the starter link, you have the one with bolts under the flywheel. I have used a thin wrench and reached under the flywheel and removed the bolts, by letting the starter down as you turn the bolts.

Where can i find that number on it?
Technician: Curtis B., Technician replied 2 years ago

On hood? Or a plate on the frame?

Ask Your Own Small Engine Question
Technician: Curtis B., Technician replied 2 years ago

It may be an MTD model, made for Bolens.

Customer reply replied 2 years ago
I havent seen anything yet although i did get closer the starter and flywheel was able to pull the gear up to match with the flywheel and wont budge on the starter alone
Technician: Curtis B., Technician replied 2 years ago

Battery voltage may not be what it needs to be! Charger may not do it!
