Old Briggs with Flow-Jet carb - Starting tips?

Hi everyone,

I've started a few threads recently about a vintage Mastercraft/MTD 8/26 from around 1979. It has a Briggs and Stratton 190 series Sno/Gard engine with a Flow-Jet carb. I replaced the carb last winter with an aftermarket one, and it's been running well since then, but sometimes it takes quite a few pulls to get it started.

This is the first small engine I've ever owned without a primer bulb and I'm wondering if anyone has any tips to make starting easier? I've read that with a carb like this it is a good idea to shut off the fuel valve at the tank when not using the machine, but I'm assuming if the machine sits for more than a few days the carb may be dry by the next time I go to use it.

So is it a good idea to turn the fuel valve on and wait awhile for the carb to fill before I start pulling on the cord? How long would it take for the carb to fill... 30 sec, 5 min, longer?

Will an engine with a carb like this ever start on the first pull when it's cold?

Any tips or suggestions would be much appreciated. I've attached a couple pics.

Thanks.

drill a hole in the carb box to accept a carb cleaner straw......squirt in carb, close choke, pull. BTW..really easy to convert that briggs to electronic ignition...just replace the coil with a modern single cylinder one....I've got a pile of blown up vertical shaft Inteks I rob...makes cleaning points a thing of the past

These are very easy starting engines even without a primer I believe due to the way that the emulsion tube jets span the entire intake...and/or that they're self priming by leaking fuel into the intake

top notch tip by cranman; the electronic ignition is very straightforward...bolt on a new coil and you're done.

Thanks for the replies. A hole in the carb box and some carb cleaner sounds like a great idea and I would have never thought about changing to electronic ignition either. I'll do some research about this, but please let me know if you have any suggestions on how to find the right coil. I have no access to used ones.
