yes grav feed will work with it enough to run, generally they can go to 5K i wont push mine that hard (freakboy) soo just run it gently, now is the time to crank it and idle it and see what happens

 

[Kaptain Krunch]

RPM range should be around that of any other industrial engine (1k-3.6k ish). Is the fuel pump part of the carb like on the briggs twins? if not you could probably get away with gravity feed. Have you cleaned the carb yet?

 

[BriggsTwins]

i wish my carb was complete, its a pre internal pump model....has the casting guts but its not drilled or set up to take a pump... IT SUCKS. i your case even if the pump is soft the bowl float will keep fuel pressure at bay

 

[zanegrey]

the fuel pump is an inline unit..

i have not cleaned the carb..it is next

now that it appears to be a good engine ... i will fab up some mounts for the dual coils and clean up the wiring ..

reinstall the shrouds ,drain and refill with fresh oil....

i guess i better get it sprayed off before i do anything else first..

 

[BriggsTwins]

do that first! clean the bowl and make sure the passages are clear. it will save you a headache or two.

 

[Kaptain Krunch]

Clean the carb then, thats the first thing i do when i get a new engine thats been sitting.

 

[zanegrey]

i am guessing that cleaning up the carb and fixing the leaky base gasket means pulling the manifold off as well.

on one side of the carb is a stud that feeds up thru the mani and the other side looks to be a stud that has a nut on it..

it looks like some one was there b 4 me because u can see the red atv gasket sealant sticking out the seam of the long axis of the intake mani..

 

[BriggsTwins]

wel take it apart CAREFULLY i dont need to tell you what would happen with screws and valves

 

[zanegrey]

i was thinking of trying to tighten down the base of the carb and then try the gravity feed to see if the carb works in it's present condition..

i really do not have access to a gasket or parts today ..

i can make some gaskets but you never know about these old machines..

 

[BriggsTwins]

yea thats ok as long as there isnt leaks or back flow into the ventura, (bowl valve malfunction)

 

[anderkart]

Hey good job Zane, I'm glad yo got-er goin. (dont be free revving that engine too high of rpms / try to find a good brand of streaght 30 weight oil, not 10-30)

 

[freakboy]

were does it say he got it running?

 

[zanegrey]

i did get it to start..

a full on start ..where the govener kicks in to stabilize the rpms..

however i have not worked out the fuel supply yet..

so i have not had it idle own its own ..


but i think it is looking good..

 

[freakboy]

oh ok good job there and a hose into a 2 liter bottle works good.

 

[BriggsTwins]

cant wait to hear this thing run

 

[zanegrey]

i have the original gas tank but i have to clean it out and hang it so that the gas gravity feeds w/o too much pressure..

u can see the tank on the left side of the engine..

i had the bobcat mower bush hog this engine came off of weighed ..it was 1700 lbs...

 

[BriggsTwins]

holy god

 

[zanegrey]

lol

update:

i got the engine sprayed off today ..

got the coil hard wired and mounted..

i used an extra long fuel line and filled it to the top and pulled it up the flag pole ..

hooked up my bat and put the juice to the starter..

it seems now it will not start with both plugs in ..

on one plug i got it to run and kind of idle ..

so i am thinking the the exhaust valve is stuck in the shut position..

that is the cylinder makes plenty of compression and it is getting gas and spark..

i put my finger over the spark plug hole as it was idleing ...kind of kills it straight away..


so i cleaned up for the day..

 

[BriggsTwins]

thats a bad sign if the valve isnt lifting...... time to crack that block open
